The formal notice of the AGM and the resolutions to be proposed are set out on pages 10 to 15 of this document. The notes on the following pages give an explanation of the proposed resolutions. Resolutions 1 to 18 are proposed as ordinary resolutions. This means that for each of those resolutions to be passed, more than half of the votes cast must be in favour of the resolution. Resolutions 19 to 23 are proposed as special resolutions. This means that for each of those resolutions to be passed, at least three-quarters of the votes cast must be in favour of the resolution. COVID-19 The Board is closely monitoring developments arising out of the ongoing COVID-19 pandemic and the Board’s priority is to safeguard the health and safety of its Shareholders and employees. As at the date of this Notice of AGM, the UK Government has moved into Step 4 of its roadmap for easing lockdown restrictions. We are therefore proposing to hold our AGM at the Company’s offices located at Cannon Bridge House, 25 Dowgate Hill, London, EC4R 2YA, and to welcome the maximum number of Shareholders we are able to within safety constraints and in accordance with government guidelines. If you do wish to attend in person, please register your intention at www.investorcentre.co.uk/eproxy no later than 14:00 on Monday, 20 September 2021. However, given the constantly evolving nature of the situation, we want to ensure that we are able to adapt these arrangements efficiently to respond to changes in circumstances. Should we have to change the arrangements, it is likely that we will not be in a position to accommodate Shareholders beyond the minimum required to hold a quorate meeting (which will be achieved through the attendance of employee Shareholders). In any case, Shareholders are also advised to consider if you are able to safely attend the meeting in person. It is recommended that Shareholders appoint the Chair of the AGM as their proxy. This will ensure that your vote will be counted if ultimately you (or any other proxy you might otherwise appoint) are not able to attend the meeting. 02 IG GROUP HOLDINGS PLC NOTICE OF MEETING 2021 36968_IG_AR21_NOM_AW.indd 2 04/08/2021 16:13 To help keep everyone safe, there will be no exhibitions and no refreshments. We may require social distancing and the wearing of face coverings, to align with UK Government guidelines or as a safety measure at the time of the meeting where appropriate. We may ask attendees to confirm that they (or members of their household) have not recently developed COVID-19 symptoms or been exposed to someone who has either tested positive for COVID-19 or is displaying COVID-19 symptoms. No guests will be allowed entry to the meeting, so attendance will be restricted to Shareholders and accompanying carers. We may also put in place other safety and security measures as a condition of admission to the venue, including, but not limited to, temperature checks. We will continue to closely monitor the latest UK Government guidance in respect of COVID-19 and how this may affect the arrangements for the AGM. Following the date of this Notice of AGM, the Company will keep under review the AGM format and any changes to the AGM will be communicated to Shareholders before the meeting on the Company’s website at www.iggroup.com and, where appropriate, by an announcement via a Regulatory Information Service. Annual Report and Accounts (Resolution 1) The Directors present to the Shareholders at the AGM for approval as an ordinary resolution the Annual Report and Accounts for the year ended 31 May 2021, together with the Directors’ and Auditors’ reports on the Annual Report and Accounts. Directors’ Remuneration Report (Resolution 2) Shareholders will be asked to receive and approve as an ordinary resolution the Directors’ Remuneration Report for the year ended 31 May 2021. The Directors’ Remuneration Report is set out in full on pages 78 to 80 of the Annual Report and Accounts and sets out the pay and benefits received by each of the Directors during the year ended 31 May 2021. This vote is advisory and therefore will not affect the remuneration or benefits received by any Director. Dividend (Resolution 3) A final dividend of 30.24 pence per ordinary share is recommended by the Directors for payment to Shareholders on the Register of Members at the close of business on 24 September 2021. Subject to the approval of Shareholders at the AGM, this dividend will be paid on 21 October 2021.
